Research on Low-complexity Decoding Method in Massive Antenna System
摘要
Abstract
In massive antenna system,the computational complexities of linear channel estimation and linear decoding are higher.Aiming at this problem,two low-complexity decoding methods are proposed according to the characteristics of massive antenna system.A fast decoding method is designed by using the asymptotic orthogonality of the channel in the system,which avoids solving the inverse matrix of the channel matrix.Since the increased number of Base Station (BS)can optimize the user's channel,a simple operator decoding method which realizes direct decoding without estimating the channel is designed.Simulation results show that these two decoding methods can reduce the computational complexity effectively while maintaining the system performance.关键词
